2833. Furthest Point From Origin

You are given a string moves of length n consisting only of characters 'L', 'R', and '_'. The string represents your movement on a number line starting from the origin 0.

In the ith move, you can choose one of the following directions:

• move to the left if moves[i] = 'L' or moves[i] = '_'
• move to the right if moves[i] = 'R' or moves[i] = '_'

Return the distance from the origin of the furthest point you can get to after n moves.

            else if(m == 'R') at -= 1;
            else any += 1;
        }

        res = max(res, abs(at - any));
        res = max(res, abs(at + any));
